Navy researchers at the U.S. Naval Research Laboratory (NRL), Materials Science and Technology Division, demonstrate proof-of-concept of novel NRL technologies developed for the recovery of carbon dioxide (CO2) and hydrogen (H2) from seawater and conversion to a liquid hydrocarbon fuel.

From AddictingInfoAnnouncing a major breakthrough, Navy researchers for the first time have converted seawater into CO2 and hydrogen, which could be used to produce jet fuel within a decade.

After decades of experiments, U.S. Navy scientists
believe they may have solved one of the world’s great challenges: how to
turn seawater into fuel.
…
The new fuel is initially expected to cost around $3 to $6 per
gallon, according to the U.S. Naval Research Laboratory, which has
already flown a model aircraft on it.

Curiously, this doesn’t seem to be making much of a splash (no pun
intended) on the evening news. Let’s repeat this: The United States Navy
has figured out how to turn seawater into fuel and it will cost about
the same as gasoline.

This technology is in its infancy and it’s already this cheap?
What
happens when it’s refined and perfected?
Oil is only getting more
expensive as the easy-to-reach deposits are tapped so this truly is, as
it’s being called, a “game changer.”

I expect the GOP to go ballistic over this and try to legislate it
out of existence.
It’s a threat to their fossil fuel masters because it
will cost them trillions in profits.
It’s also “green” technology and
Republicans will despise it on those grounds alone.
They already have a track record of trying to do this.
Unfortunately, once this kind of genie is out of the bottle, it’s very hard to put back in.

The Navy fleet line, but could be doing so under steam of a new kind of fuel.

The Navy’s 289 vessels all rely on oil-based fuel,

with the exception of some aircraft carriers and 72 submarines that rely on nuclear propulsion.

There are two other aspects to this story that have not been brought up yet:

The process pulls carbon dioxide (the greenhouse gas driving
Climate Change) out of the ocean. One of the less well-publicized
aspects of Climate Change is that the ocean acts like a sponge for CO2
and it’s just about reached its safe limit. The ocean is steadily
becoming more acidic from all of the increased carbon dioxide. This in
turn poisons delicate ecosystems like coral reefs that keep the ocean
healthy.

If we pull out massive amounts of CO2, even if we burn it again, not
all of it will make it back into the water. Hell, we could even pull
some of it and not use it in order to return the ocean to a sustainable
level. That, in turn will help pull more of the excess CO2 out of the
air even as we put it back. It would be the ultimate in recycling. This will devastate oil rich countries but it will get us the hell
out of the Middle East (another reason Republicans will oppose this).
Let’s be honest, we’re not in the Middle East for humanitarian reasons.
We’re there for oil. Period. We spend trillions to secure our access to
it and fight a “war” on terrorism. Take away our need to be there and,
suddenly, justifying our overseas adventures gets a lot harder to sell.

And if we “leak” the technology?
Every dictator propped up by oil
will tumble almost overnight.
Yes, it will be a bloody mess but we won’t
be pissing away the lives of our military to keep scumbags in power.
Let those countries figure out who they want to be without billionaire
thugs and their mercenary armies running the show.

Why this is not a huge major story mystifies me.
I’m curious to see how it all plays out so stay tuned.

UPDATE:
People have been asking for more details about the process.
This is from the Naval Research Laboratory’s official press release:

Using an innovative and proprietary NRL electrolytic
cation exchange module (E-CEM), both dissolved and bound CO2 are removed
from seawater at 92 percent efficiency by re-equilibrating carbonate
and bicarbonate to CO2 and simultaneously producing H2. The gases are
then converted to liquid hydrocarbons by a metal catalyst in a reactor
system.

In plain English, fuel is made from hydrocarbons (hydrogen and
carbon).
This process pulls both hydrogen and carbon from seawater and
recombines them to make fuel.
The process can be used on air as well but
seawater holds about 140 times more carbon dioxide in it so it’s better
suited for carbon collection.

Another detail people seem to be confused about: This is essentially a
carbon neutral process.
The ocean is like a sponge for carbon dioxide
in the air and currently has an excess amount dissolved in it.
The
process pulls carbon dioxide out of the ocean.
It’s converted and burned
as fuel.
This releases the carbon dioxide back into the air which is
then reabsorbed by the ocean.
Rinse.
Repeat.
